j To all whom it may concern: L

Be it known that l, 'iLLIAM II. SHINN, of Carnegie,

in the county of Allegheny and State .of Pennsylvania, have invented "a new and 'useful improvement in 5 Pressed-Steel Journal-Boxes for Railway-Cars,of`

which the following is a full, clear, and exact description, reference being had to the accompanying draw-A ing, forming part of this specificatiomin which- Figure l a plan View ofthe blank of the lug-plate;` f 10 Fig. 2 is aside elevation of the lug-plate'after it has been bent and forged into shape; Fig. 3 is a front elevation ofthe saine; Fig. 4is a vertical sectional view l of a journal-box showing the lug-plate in position and riveted to the botlyof the box; Fig. fis a plan view of ticnoi the lug-plate; Fig. 7 is a side. elevation of the same; and Fig. 8 is arear elevation ofthe saine.

i My invention relates to an improvement in journali boxes for railwaycars and-it consistsin a journal-box ing a lug-plate'provided with depending flanges or plugs and a hinge flange'or lug, this plate and these .flanges or lugs being formed in one piece, the plate being of such form as to act a reinforcement to the In Fig. l of the drawing, 2 represents the blank from which the lug-plate is formed. 'Thisblank is cut to the shape shown in the drawing and may be provided with rivet holes 1. The wings a b are then bent under drop forging, or by other suitable means, to the finished lug-plate shown in Figs. 2, 3, 4, and. The

' blank 2, in addition to the wings and leaves a', b, and e, is provided with front leaves d, d, and e. The eiecii downwardly Vtor a substantially vertical position, to i weld the wings a, b, and the leaf c together and to corrugate the same, thusforming the depending side lugs 3. The irontfleaves d,d and e are bent upwardly, the

Y f end horizontally, or slightly downwardly, backward, thus forming the spring base flange or restV 5, against which the spring of the box lid is adaptedxto press, and the leaves d, d, being curled upwardly and backwardly' forming the hinge ilange or socket 4; The lug-plate 8 so formed is adapted to be part of a pressed steel jour# nal box, such a journal box o being shown in Figs. 4 and 5 of the dmwings. 'lhis box is formed in one piece,

i having a butt or overlapping seam in the upper portion l f: `1me,ssED-s'rrnsn.roURNAL-Box FoRnAILwnY-cnns.

. united vby. welding or by rivets'or bolts, or other equiva-V 4liable to injury or breakage. Heretoforein pressed y l i lquired. By iny improvement the boxisfstrengthened f portion formed of n single piece of pressed steel, the upper .u ,lug plate lapping the seam of the body portion and Re- 1PATENToFFif` lent means. This brings thecorrugated flanges or lugs j 3 of Athe plate 3 within the corrugated side depending v flanges or ribs 10v of the Vjournal box, the side .lugs 3l 55 l' i' i serving as a reix'iforceinent to the ribs 10,'between which i ribs or corrugations is the groove or cavity 1l for the reception n of the arch bar bolts. The depending l flanges or lugs 3 also serve as Vrests or stops for the 'brasses or bearings of the journal box. At the forward 60 end' of the lug-plate 8, on each :side of the lug 4, are lugs v 12 which are bent downwardly from the body'foi the blank 2 in the drop forgingoperation and serve as i i rest for the stop Wedge of the journalfbox. f v y In Figs. (i, 7, and 8 l have shown a modification in 65 which the hinge flange or lug 4 and the spring base flange or rest lug 5 are formed by drop forging of a single solid lug integral vwith the plate 8 in which a cavity 13 for the pintle ofthe hinge is drilled. The corrugated side dependingflanges lugs 14 are also 70 formed bydrop iorging in solid parts of metal integral with the plate S". ln place of forging the-plate 8 it may be cast, but l` prefer the pressing or forging. y

'.lhe ladvantages of my invention will be appreciated f by those skilled in the art. it is wellknown that the 7 5 f ,hinge` lugs and spring'rback rest of journalr boxes are steel journal -boxes,'such lugs have been generally v i formed in a separate piece which has been welded or riveted to the top reinforcing plate of the box. By 80 my improvement lam able to form the plate and .theseV ,I lugs in one piece. By corrugating the side lugs I .am l enabled to reinforce the bolt groove in a .pressed steel,` box at that point where the greatestfstrength is re,

and lightened.

Having thus describedl my invention, what I claim and desire to secure by Letters Patent is l 1. in a pressed steel journalbox having a body portion, i 1 a reinforcing lug plate adapted .to be secured to the top of thi-box, said lug plate being provided kwith depending g. flanges and with an upwardly extendinghinge flange, the

flanges und plate being-formed in one piece.
